Create docs/user-guide.md covering all dashboard features from the
perspective of a security engineer. Includes getting started, all
page workflows (Home, Triage, Compliance, CCP Metrics, Knowledge Base,
Exports, Jira, Archer Templates), user settings, admin features
(View As, scope toggle), and tips/best practices for daily triage.
No code references, deployment steps, or technical implementation
details — purely operational guidance for end users.
